CHIMNEY CLEANER.

Application filedJanuary 10, 1822. Serial No. 528,142.

To all whom it may concern:

Be it known thatI, JOHN G. KoUnnLKA, a citizen of the United States, and resident of Antigo, in the county of Langlade and State of Wisconsin, have invented certain new and useful Improvements in Chimney Cleaners; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to a new and improved chimney cleaner and its principal object is the provision of a device of this character which may be conveniently moved from place to place and which may easily and quickly be placed in position for operation or removed therefrom.

It is also an object of the invention to provide a device of this kind having a reservoir for containing compressed air which may rest on the floor or ground beside the chimney and has a conduit leading therefrom which may readily be inserted into the chimney for the purpose of discharging the air suddenly at a predetermined time.

A still further object of the invention is the provision of means whereby the reservoir may be charged at a pumping station in preparation for use and thereby obviating the necessity manually.

Vith the above and other objects in view the invention comprises certain details of construction and combinations of parts which will be hereinafter described in connection with the accompanying drawing, in which Figure 1 is a sectional view of a chimney flue with my invention connected therewith ready for use.

Figure 2 is a view showing in elevation a modified form of my invention, and

Figure 3 is a view showing a further modification of my invention.

Referring by reference characters to the drawing, the numeral 1 indicates a reservoir which is adapted to contain compressed air or other fluid under high pressure and having an inlet 2 through which the fluid is introduced, said inlet being controlled by a valve 3. In Figure 1, I have shown a manually operable air pum 4 connected to the inlet in position for filllng the reservoir but it will of course be understood that the reservoir may connected with any hose for of creating the pressure supplying air such for instance, as will be found at any gasoline supply station.

The reservoir is provided with an outlet conduit 5 having a pressure gauge 6 and a valve 7 for controlling the discharge of the fluid from the reservoir. A flexible hose 8 may be connected with the conduit 5 as shown in Figure 2 or a discharge pipe 8 may be used in place of hose as shown in Figure 1. At the outer end of the hose or pipe an outlet nozzle 9 is attached which is provided with a perforated cap 10. A breakable disc or diaphragm 11 may be inserted between the cap and the nozzle which will prevent the escape of the fluid until a predetermined pressure is brought to bear on the diaphragm.

In using the form shown in Figure 1 the pipe 8 is inserted through the opening 12 in the wall of the flue and preferably a thimble 13 is eccentrically mounted on the pipe which provides a closure for the remainder of the opening. Thus it will be seen that the device may be adapted to reach openings at different heights by revolving the thimble about the pipe 8. From the foregoing description it will be seen that I have provided a device which may be very readily moved from place to place and quickly inserted for operation in the flue. The diaphragm 11 retains the fluid until a predetermined pressure is exerted whereupon the diaphragm will break and the fluid will be suddenly discharged with high velocity. The sudden movement or jar occasioned by this discharge will loosen the particles which adhere to the sides of the flue and the lighter particles will be blown out of the top of the chimney while the heavier particles fall to the bottom.

In the modified form shown in Figure 3. the reservoir 13 is so constructed that it may be inserted bodily into the chimney hole. The cap M is located in the end of the reservoir which is cut away, as shown at 15, to permit the cap to be contained within the contour of the reservoir. A collar 16 is fitted around the reservoir and the latter may be inserted to any depth desired according to the size of the chimney.

\Vhile I have shown several forms in which my invention may preferably be embodied, it will be understood that other modifications embodying the principles of my invention may readily be devised. It is my intention, therefore, to include all such modifications Within the scope of the appended claim.

I claim as my invention A chimney cleaner comprising a reservoir for fluid under pressure, means for forcing fluid into said reservoir, a conduit leading from said reservoir and adapted to be inserted Within a flue opening, a removable cap for the extreme outer end of said conduit and a removable diaphragm held in sealing relation to the extreme outer end of said conduit by said cap, said diaphragm being adapted to rupture when a pre-deter mined fluid pressure is reached, whereby the entire system is subjected to uniform fluid pressure up to the extreme end of said conduit at the instant rupture of said diaphragm occurs.

In testimony that I claim the :loregoing I. have hereunto set my hand at Antigo, in the county of Langlade and State of Wisconsin.

JOHN G. KOUDELKA.
